Every address gets added with TENTATIVE flag even for the addresses with
IFA_F_NODAD flag and dad-work is scheduled for them. During this DAD process
we realize it's an address with NODAD and complete the process without
sending any probe. However the TENTATIVE flags stays on the
address for sometime enough to cause misinterpretation when we receive a NS.
While processing NS, if the address has TENTATIVE flag, we mark it DADFAILED
and endup with an address that was originally configured as NODAD with
DADFAILED.
We can't avoid scheduling dad_work for addresses with NODAD but we can
avoid adding TENTATIVE flag to avoid this racy situation.

Device node iterators put the previous value of the index variable, so an
explicit put causes a double put.
In particular, of_mdiobus_register can fail before doing anything
interesting, so one could view it as a no-op from the reference count
point of view.

Macvlan always turns on offload features that have sofware
fallback (NETIF_GSO_SOFTWARE). This allows much higher guest-guest
communications over macvtap.
However, macvtap does not turn on these features for vlan tagged traffic.
As a result, depending on the HW that mactap is configured on, the
performance of guest-guest communication over a vlan is very
inconsistent. If the HW supports TSO/UFO over vlans, then the
performance will be fine. If not, the the performance will suffer
greatly since the VM may continue using TSO/UFO, and will force the host
segment the traffic and possibly overlow the macvtap queue.
This patch adds the always on offloads to vlan_features. This
makes sure that any vlan tagged traffic between 2 guest will not
be segmented needlessly.

commit d98ecdaca2 ("arm64: perf: Count EL2 events if the kernel is
running in HYP") returns -EINVAL when perf system call perf_event_open is
called with exclude_hv != exclude_kernel. This change breaks applications
on VHE enabled ARMv8.1 platforms. The issue was observed with HHVM
application, which calls perf_event_open with exclude_hv = 1 and
exclude_kernel = 0.
There is no separate hypervisor privilege level when VHE is enabled, the
host kernel runs at EL2. So when VHE is enabled, we should ignore
exclude_hv from the application. This behaviour is consistent with PowerPC
where the exclude_hv is ignored when the hypervisor is not present and with
x86 where this flag is ignored.

The cmpxchg implementation introduced by commit c342f78217 ("arm64:
cmpxchg: patch in lse instructions when supported by the CPU") performs
an apparently redundant register move of [old] to [oldval] in the
success case - it always uses the same register width as [oldval] was
originally loaded with, and is only executed when [old] and [oldval] are
known to be equal anyway.
The only effect it seemingly does have is to take up a surprising amount
of space in the kernel text, as removing it reveals:

During my research I found that some of the requirements for the memory
buffers for MFC v6+ devices were blindly copied from the previous (v5)
version and simply turned out to be excessive. The relaxed requirements
are applied by the recent patches to the MFC driver and the driver is
now fully functional even without the reserved memory blocks for all
v6+ variants. This patch removes those reserved memory nodes from all
boards having MFC v6+ hardware block.

This fixes the new ept_access_test_read_only and ept_access_test_read_write
testcases from vmx.flat.
The problem is that gpte_access moves bits around to switch from EPT
bit order (XWR) to ACC_*_MASK bit order (RWX). This results in an
incorrect exit qualification. To fix this, make pt_access and
pte_access operate on raw PTE values (only with NX flipped to mean
"can execute") and call gpte_access at the end of the walk. This
lets us use pte_access to compute the exit qualification with XWR
bit order.
